It has to do with the way the pigment organelles, or melanosomes, within the skin cells are distributed. In the skin cells of most of the body (glabrous skin), the melanosomes are all basically separate, while in skin cells of the palms and soles (volar skin), the melanosomes tend to form into complexes-basically just groups of previously ordinary melanosomes all enveloped in another membrane. Something about the way these groups operate, or simply something about the way they appear on a macroscopic level, is different from the way individual, ungrouped melanosomes are, leading to lighter colours.
This same difference in colour actually occurs in Caucasian people as well as Africans and African-Americans, but because Caucasian people tend to have mostly these grouped melanosomes in both types of skin instead of having only free-floating pigment bags in the glabrous skin, the difference in colour between their palms and the rest of their skin is much subtler.
For example Africans in the south are really dark. In the east they are tannish brown. In the west they are fairly dark. In the north they are a little tan or white. In the central they are a mix with all of the above. So africans are many different colors.
Skin color is the pigmentation of your skin based on the amount of melatonin in the cells. Less melatonin means lighter skin color; more is darker.
In general, the trend is toward large sizes. In particular larger bags with a lighter tan or straw color.

Yes! In fact in places like Africa darker skin people use bleaching creams to make their skin lighter.
